1. A computer peripheral tester for testing a serial or parallel data communication computer peripheral having a data communication cable, the computer peripheral being external to a computer, comprising:

  • central processing means;

    memory means for storing data and control program instructions executed by the central processing means;

    keypad input means for inputting commands to the central processing means;

    display means, responsive to the central processing means, for displaying characters;

    serial communcation interface means for converting parallel data from the central processing means to serial data and serial data to parallel data input to the central processing means;

    parallel communication interface means interfacing the central processing means to the computer peripheral for parallel data communication;

    the serial and parallel communication inteface means operating at different voltage levels;

    connecto means including a plurality of contacts for releasable connection to the data communication capable attached to a computer peripheral;

    bus means for connecting the central processing means, the memory means, the keypad input means, the display means, the serial communication interface means, and the parallel communication interface means in data communication; and

    serial/parallel switch means, connected to the connector means, the serial communication interface means and the parallel communication interface means, for selectively connecting the serial communication interface means and the parallel communication interface means to the connector means for one of serial and parallel data communication, respectively, between the central processing means and the computer peripheral.
